| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
Tried to close positive contactor but failed because a voltage match was not maintained.
|
Contactor state timed out of PULLED_IN because a voltage match was not maintained.
|
Positive pack contactor will remain open.
|
|
|
Tried to close negative contactor but failed because the coil drive current was too low.
|
Contactor state timed out of PULLED_IN because of insufficient contactor coil current.
|
Negative pack contactor will remain open.
|
|
|
Tried to close positive contactor but failed because the coil drive current was too low.
|
Contactor state timed out of PULLED_IN because of insufficient contactor coil current.
|
Positive pack contactor will remain open.
|
|
|
Did not try to close negative contactor because a voltage match was not achieved.
|
Contactor state is OPEN and the PULLED_IN state has been blocked for more than 10s because a required HV voltage match has not been achieved.
|
Negative pack contactor will remain open.
|
|
|
Did not try to close positive contactor because a voltage match was not achieved.
|
Contactor state is OPEN and the PULLED_IN state has been blocked for more than 10s because a required HV voltage match has not been achieved.
|
Positive pack contactor will remain open.
|
|
|
Contactor opened unexpectedly due to insufficient contactor drive voltage.
|
Contactor control state exited CLOSED because of insufficient contactor power voltage.
|
Vehicle may lose propulsion or be unable to support LV system.
|
|
|
Pack contactor exited the economized state unexpectedly. Possibly insufficient coil drive current.
|
Contactor control state exited CLOSED because either of the contactors exited ECONOMIZED.
|
Vehicle may lose propulsion or be unable to support LV system.
|
|
|
Tried to close pack contactors but failed because a voltage match was not maintained.
|
Contactor control state exited CLOSING due to voltage match being lost.
|
Pack contactors will remain open.
|
|
|
Pack contactors were blocked from opening due to high current. Pyro deployed instead.
|
Pack current is above threshold while trying to open pack contactors.
|
The positive and negative pyro fuses will be deployed.
|
|
|
An overcurrent event was detected by hardware, or ER has failed resulting in a pyro fuse deployment.
|
Passive pyro fuse deployment was detected
|
Subpack is offline
|
|
|
Pyro fuse deployment was triggered but did not execute.
|
Software did not successfully deploy the pyro
|
Pyro deployment may be compromised
|
|
|
Pyro fuse deployment was triggered by firmware.
|
Pyro fuse deployment was triggered by firmware
|
Subpack is offline
|
|
|
Pyro fuse may not have cleanly blown, post-mortem diagnostic.
|
Energy and/or charge delivered to the squib were out-of-tolerance
|
Pyro deployment may be compromised
|
|
|
Pyro fuse is faulted.
|
Leak test failure or Switch test failure or other failure
|
Pyro fuse deployment ability is compromised
|
|
|
Pyro squib is disconnected or open-circuit, but pyro circuit is otherwise nominal.
|
Pyro squib is missing resulting in open-circuit resistance
|
Pyro fuse deployment ability is compromised
|
|
|
Fault impacting the pyro sub-system.
|
Pyro operations could not be started
|
Pyro cannot be deployed
|
|
|
Energy-reserve circuit has a failure.
|
Voltage of the energy-reserve is out-of-tolerance
|
Pyro deployment may be compromised
|
|
|
Indicates a BMB reference voltage has continuously been out of bounds.
|
Any BMB reference voltage has continuously deviated outside the in-bounds threshold of the nominal voltage
|
Other BMB voltage signals will be substituted given the reference voltage is unreliable
|
|
|
Indicates a mismatch between a stack voltage and the sum of its brick voltages.
|
Any BMB continuously has a stack voltage that doesn't align with the sum of its brick voltages within the in-bounds tolerance
|
BMB stack and brick voltage signals will be substituted
|
|
|
HVPACK cannot talk to all BMBs.
|
A communication issue with the BMB daisy chain is detected
|
May indicate a loss of BMB sensor data
